We hearken to the man of science, because we anticipate the sequence in natural phenomena which he uncovers.

Ralph Waldo Emerson

Do to others as you would have others do to you, inspires all men with that other maxim of natural goodness a great deal less perfect, but perhaps more useful: Do good to yourself with as little prejudice as you can to others.

Jean-Jacques Rousseau

When you wish to see whether the general effect of your picture corresponds with that of the object represented after nature, take a mirror and set it so that it reflects the actual thing, and then compare the reflection with your picture, and consider carefully whether the subject of the two images is in conformity with both, studying especially the mirror. The mirror ought to be taken as a guide... you see the picture made upon one plane showing things which appear in relief, and the mirror upon one plane does the same. The picture is on one single surface, and the mirror is the same.... if you but know well how to compose your picture it will also seem a natural thing seen in a great mirror.

Leonardo da Vinci

Let mental culture go on advancing, let the natural sciences progress in even greater extent and depth, and the human mind widen itself as much as it desires: beyond the elevation and moral culture of Christianity, as it shines forth in the Gospels, it will not go.

Johann Wolfgang von Goethe

Renunciation which is natural does not herald its coming by the blowing of trumpets. It comes in imperceptibly without letting anyone notice it.

I fully agree with all that you say on the advantages of Spencer's excellent expression of 'the survival of the fittest.' This, however, had not occurred to me till reading your letter. It is, however, a great objection to this term that it cannot be used as a substantive governing a verb; and that this is a real objection I infer from H. Spencer continually using the words, natural selection.

His talent was as natural as the pattern that was made by the dust on a butterfly's wings. At one time he understood it no more than the butterfly did and he did not know when it was brushed or marred. Later he became conscious of his damaged wings and of their construction and he learned to think and could not fly any more because the love of flight was gone and he could only remember when it had been effortless.

Ernest Hemingway

It is now no more that toleration is spoken of, as if it was by the indulgence of one class of people that another enjoyed the exercise of their inherent natural rights.

George Washington

The heart has its sabbaths and jubilees in which the world appears as a hymeneal feast, and all natural sounds and the circle of the seasons are erotic odes and dances.

Ralph Waldo Emerson

I make no doubt... that these rules are simple, artless, and natural.

It is also a natural thing for a serious young man that he should form for himself as precise an idea as possible of the goal of his desires.

Albert Einstein

Collective wisdom, alas, is no adequate substitute for the intelligence of individuals. Individuals who opposed received opinions have been the source of all progress, both moral and intellectual. They have been unpopular, as was natural.

Bertrand Russell

A desire for knowledge is the natural feeling of mankind; and every human being, whose mind is not debauched, will be willing to give all he has to get knowledge.

A human being has a natural desire to have more of a good thing than he needs.

This pride of race is a quality which the German, fundamentally, does not possess. The reason for this is that for these last three centuries the country has been torn by internal dissension and religious wars and has been subjected to a variety of foreign influences, to the influence, for example, of Christianity—for Christianity is not a natural religion for the Germans, but a religion that has been imported and which strikes no responsive chord in their hearts and is foreign to the inherent genius of the race.

For first of all we must prepare a Natural and Experimental History, sufficient and good; and this is the foundation of all; for we are not to imagine or suppose, but to discover, what nature does or may be made to do.

Our design, not respecting arts, but philosophy, and our subject, not manual, but natural powers, we consider chiefly those things which relate to gravity, levity, elastic force, the resistance of fluids, and the like forces, whether attractive or impulsive; and therefore we offer this work as mathematical principles of philosophy; for all the difficulty of philosophy seems to consist in this — from the phenomena of motions to investigate the forces of nature, and then from these forces to demonstrate the other phenomena...

Although much remains obscure, and will long remain obscure, … I am convinced that Natural Selection has been the main but not exclusive means of modification.

When the views advanced by me in this volume, and by Mr. Wallace, and when analogous views on the origin of species are generally admitted, we can dimly foresee that there will be a considerable revolution in natural history.

Our nuclear power plants have undergone exhaustive study, and have been declared safe for any number of extreme contingencies. But when we see a crisis like the one in Japan, we have a responsibility to learn from this event, and to draw from those lessons to ensure the safety and security of our people.
That's why I've asked the Nuclear Regulatory Commission to do a comprehensive review of the safety of our domestic nuclear plants in light of the natural disaster that unfolded in Japan.

'You're frightfully BBC in your language this afternoon, Albert,' said Tuppance, with some exasperation.
Albert looked slightly taken aback and reverted to a more natural form of speech.
'I was listening to a very interesting talk on pond life last night,' he explained.

Agatha Christie

To suppose that the eye with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I freely confess, absurd in the highest degree.

The observance of Thanksgiving Day-as a function-has become general of late years. The Thankfulness is not so general. This is natural. Two-thirds of the nation have always had hard luck and a hard time during the year, and this has a calming effect upon their enthusiasm.

Little else is requisite to carry a state to the highest degree of opulence from the lowest barbarism, but peace, easy taxes, and a tolerable administration of justice; all the rest being brought about by the natural course of things.

I have obtained... spark discharges extending through more than one hundred feet and carrying currents of one thousand amperes, electromotive forces approximating twenty million volts, chemically active streamers covering areas of several thousand square feet, and electrical disturbances in the natural media surpassing those caused by lightning, in intensity.
Whatever the future may bring, the universal application of these great principles is fully assured, though it may be long in coming. With the opening of the first power plant, incredulity will give way to wonderment, and this to ingratitude, as ever before.
